Interpretation Introduction

Interpretation: An explanation corresponding to the statement that ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{Br}$ is not formed during the radical bromination of ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}$ is to be stated.

Concept introduction: The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. The electron rich chemical species that contains negative charge or lone pair of electrons are known as nucleophile. In nucleophilc aromatic substitution reaction, nucleophile takes the position of leaving group by addition-elimination reaction or by elimination-addition reaction.
